Discovery. Discovery on Request. By written request served on the other party and filed with the Board or the Office of Administrative Hearings, as appropriate, a party may require another party to produce, within 15 days, the following: A list of witnesses to be called; Copies of documents intended to be produced at the hearing; or Both §A(1)(a) and (b) of this regulation. Mandatory Discovery. Each party shall provide to the other party not later than 15 days before the prehearing conference, if scheduled, or 45 days before the scheduled hearing date, whichever is earlier: The name and curriculum vitae of any expert witness who will testify at the hearing; and A detailed written report summarizing the expert's testimony, which includes the opinion offered and the factual basis and reasons underlying the opinion. If the Board or the Office of Administrative Hearings, as appropriate, finds that the report is not sufficiently specific, or otherwise fails to comply with the requirements of this section, the Board or the Office of Administrative Hearings, as appropriate, shall exclude from the hearing the testimony of the expert and any report of the expert. The Board or the Office of Administrative Hearings, as appropriate, shall consider and decide arguments regarding the sufficiency of the report: At the prehearing conference, if scheduled; or Immediately before the scheduled hearing. If an expert adopts a sufficiently specific charging document as the expert's report, that adoption satisfies the requirements set forth in this section. Parties are not entitled to discovery of items other than as listed in §A(1) and (2) of this regulation. Both parties have a continuing duty to supplement their disclosures of witnesses and documents. Absent unforeseen circumstances which would otherwise impose an extraordinary hardship on a party, witnesses or documents may not be added to the list: After the prehearing conference, if scheduled; or Later than 15 days before the hearing, if no prehearing conference is scheduled. The prohibition against adding witnesses does not apply to witnesses or documents to be used for impeachment or rebuttal purposes. Construction.
